Resolve a communication issue with YAZ

Update 04/30/2026

This guide concerns YAZ, a software library used to implement the Z39.50 protocol, an information retrieval protocol that enables communication between different library management systems (LMS) such as PMB, widely used in France.

 

Infomaniak for efficient library management

On Infomaniak's Web Hosting, PMB is supported and YAZ is activated by default.

However, if you encounter errors such as Call to undefined function yaz_connect(), you will need to open ports via the Manager. Port 210 is the standard port used for Z39.50 communications, but do not hesitate to consult the documentation of your applications.

For older Infomaniak hosting plans, consider changing your offer.
